"Arsenal have got off to a great start, not only with their results but their performances as well.
"They are flying at the moment but it's a long season and teams always go through bad spells. It's how you react to those bad spells that counts.
"So it will be interesting to see, if and when they go through their bad patch, how they react to it. That's always the true test of a great side.
"Arsenal's confidence is high. They won the double last year and have carried on at the start of this season.
"They've got great players and a great squad but it's a long season. Every team has good and bad spells so we'll just have to wait and see how they cope."
